But even Python requires installing the dev environment etc.
I can see the use for this, for throwing people with no experience into "coding right away".
If you just apt-install IDLE I think you can be up and running very quickly. I did a relatively thorough survey when I first started learning python a couple of years ago and found PyCharm simpler for the course I was doing -- basic text handling, and a little CLI based interactive stuff.
